You cannot in alpha
Minecraft Alpha came out in 2009.
Minecraft is no longer in the Alpha stage. It has been updated to Minecraft Beta. Update your Minecraft game client.
You need an a jar from alpha stages, which you can get with Minecraft Nostalgia.
you get bones and put that bone in one crafting spot to get bonemeal (im a minecraft player since alpha)
Alpha is no longer around. If your still interested in starting a Beta server, go to the Minecraft site and download the necessary files. More info can be found on the MC Wiki.
You can no longer do multiplayer in alpha. Minecraft has moved to Beta now, so there are no more alpha servers. Update the game, and then you can play multiplayer.
Minecraft Alpha is no longer on sale, the whole game is fully out. You can get it at the website for about 30 dollars USD.
Beds were not introduced into Minecraft until Beta 1.3, so no.
Alpha was an earlier version on minecraft beta, it has poorer graphics, less blocks and far fewer crafting recipes.
Yes.
You can't play minecraft alpha 1.2.6. You can currently play minecraft beta 1.8 if you buy the game for $21.95 and then play it in the browser or download it to your computer and play it in an application. Alpha 1.2.6 is long gone, and it is not able to be found anywhere, as far as I know.
